Escalators and stairs Where we go from here Sound Transit Citizen - PowerPoint PPT Presentation

Escalators and stairs Where we go from here Sound Transit Citizen Oversight Panel December 6, 2018

Why we’re here • Escalator performance at UW Station has not met customer or agency expectations • Customers have repeatedly experienced major disruptions • We have a plan to fix the problem 2

Why we’re here Maintenance cost Frequency of outages per unit 3.6x 4.5x Capitol Hill UW Capitol Hill UW 3

What we’ve done • Studied options for maintaining or modernizing current escalators vs. replacing all units • Conducted Total Cost of Ownership (TCO) analysis • Developed preliminary replacement timelines 4

Why replacement? • Less expensive to replace now than maintain current units through expected end of useful life (2025) • Better reliability for customers years sooner 5 5

What we’re doing Complete Execute emergency stair protocol Done 1. Complete repairs recommended by consultant Q4 2018 2. Transfer UW maintenance to manufacturer Q4 2018 3. Convert back stairs for full-time use Q1 2019 4. Connect sub-mezzanines 2019 5. Replace two down escalators with stairs 2019-2022 6. Replace the other 11 escalators 2019-2022 7. 6

Downtown Seattle transit tunnel • Taking ownership from King County Metro in 2020 • Unknown scope of maintenance needs • Inheriting 36 escalators and 22 elevators 13 13

Bottom line • UW & Capitol Hill will have public stairs by early 2019. U District Station will have public stairs upon opening. • • We will replace all UW Station escalators. • Staff will return to the Board to authorize funds in 2019. UW replacement begins in 2019, complete in 2022 • 14 14

Message to our riders We apologize. • We have learned valuable design & procurement lessons. • • We have a plan. • Any station with escalators will also include stairs. • We will only install heavy duty escalators. Future elevated or tunnel stations will have redundant • access. 15 15
